- tributing cylinder or heater.

The purpose of the invention is to provide a distributing cylinder orbeater for spreading manure or a fertilizer of any description, andwhich will be simple in construction and reliable in operation, thedistributing cylinder being so constructed that it will not onlyseparate and practically pulverize the manure, but will also scatter thesame broadcast over a greater area than that occupied by the machine.

In the accompanying drawings forming 'a part of this specification,Figure 1 is a perspective view of the distributing cylinder or beater;Fig. 2' is a plan view of the same; Fig. 3 is an end view of thecylinder; and Fig. 4 is a view on a reduced scale, showing the cylinderor beater in position at the rear end of the body of a vehicle.

Like characters of reference indicate corresponding parts in all theviews.

The cylinder or beater B is mounted to revolve at the open rear end ofthe body A of a wagon and is adapted to pulverize or otherwise reduceand to distribute the manure or fertilizer fed thereto. This cylinder orbeater B is constructed with opposing heads 17 "having radial openings18 therein, that facilitate the escape of material-at the ends of thecylinder and render the heads light, and at corresponding side edges. ofthe said openings 18, outwardlyfiared flanges 19 are produced that serveto facilitate the spreading of the manure. The cylinder is provided witha shaft 20 to which the heads are secured and that extends beyond saidheads. The right=hand end of the peripheral portions of said heads. Byprefment with a connecting r0 control of the operator.

erence the heads also carry segmental braces 24 for. the bars 23. It isnot necessary that 3 these braces extend between all of the bars 23, butwhen employed, they have curved spurs 22 wherever they can beadvantageously employed, that facilitate the work of pulverization anddistribution, since the cylinder or beater B as a whole is located between the sides of the body A.

The principal work of pulverizing and distributing the manure isperformed by two series of saw-tooth blades, spirally arranged inopposite directions around the exterior of the cylinder B between itsheads.

-One series of said blades is designated as 25, the right-hand series,while the other or left-hand series, is designated as 26. These blades25 and 26 extend from points at each side of the center of the cylinderB to its heads of the other ends of the bars 23, as is best shown inFig. 2. In the arrangement of the'series'of saw-tooth blades 25 and 26,the blades of one series at their inner ends terminate opposite, yetremoved from, approximately the central portion of the next series. Thisconstruction of cylinder or beater not only pulverizes the manure, butscatters it to such an extent that the manure is delivered In a swathmuch wider than the length of the cylinder and'the width ofthe body ofthe wagon on which the cylinder is mounted. I T

The cylinder or heater B is driven from a gear 37 at the left-hand endortion of the rear axle 10 of the wagon, an a chain connection 38between said gear and a pinion 39 on a short shaft 40 secured to abracket 40", as is shown in Fig. 4, and the pinion 39 is attached to alarger gear 40, adapted for driving engagement with a pinion 41, carriedby a lever arm 42, also shown in Figs.

1 and 4, which lever arm is fulcrumed at its lower end'to said bracket40", as is shown in dotted lines at 43 in Fig. 4. The upper end of thesaid lever arm 42 has (pivotal engage- -44 under the The pinion 41, inaddition to being carried by the arm 42, is fast upon the shaft 20 ofthe cylinder, and said arm constitutes the bearing for the left hand endof thecylinder shaft. Thus as the cylinder shaft is mounted in swinbearings, by actuating the connecting re 44, the cylinder is movedbodily to carry the pinion 41 out of mesh with the gear 40 to stop therotation of the cylinder.

Suitable pivotally-mountd spring-controlled combs 78 are provided tokeep the teeth of the blades 25 and 26 clean.

Having thus described my invention, .1.

claim as new and desire to secure by Letters ,Ifatent: ,'1. In a manureor fertlhzer spreader, a

distributing cylinder or beater, comprising a skeleton frame, and seriesof oppositelydisposed spirally arranged saw tooth blades that throw thematerial beyond the ends of the cylinder.

2.-. In a manure or fertilizer spreader, a distributing cylinder orbeater, comprising a skeleton frame, and series of oppositelyoperatingthe same, which cylinder consists of opposing heads having openings andflanges at the corresponding walls of the openings, and opposingspirally-arranged saw-tooth blades, that extend from points atthe endsof the cylinder to points near its center, the terminals of the bladesof one series stopping short of a point intermediate the ends of theother series of blades.

5. In a manure or fertilizer spreader, a cylinder or beater, and meansfor optionally o erating the same, which cylinder consists of opposingheads, having openings and flanges at the corresponding walls of theopenings, and opposing spirally-arranged saw-tooth blades, that extendfrom points at the ends of the cylinder to points near its center, theterminal of the blades of one series stopping short of a pointintermediate the ends of the other series of blades, and v oppositeapproximately the central'portion of the blades of the other series.

7. In a manure or fertilizer spreader, a cylinder or beater comprisingheadshaving openings therein, a shaft to which the heads are secured,bars extending from one head to the other and secured to the peripheryof said heads, series of oppositely disposed saw-tooth blades spirallysecured upon the said bars, and means for rotating the cylinder.

8.'In a manure or fertilizer spreader, a cylinder 0r beater comprisingheads having radial openings therein and outwardly flared flanges atcorresponding side edges of said openings, a shaft to which the headsare secured, spaced bars extending from one head to the other andsecured to the periphery of the heads, series-of oppositely disposedspiral blades secured to said bars, an means for rotating the cylinder.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
